Rate limit
To prevent server abuse, API requests made to the server are limited to 240 megapixels per minute for Enterprise licenses.
The rate limit has a sliding window of one minute. When the server request is made,
the sum of all image sizes sent within the last minute is checked and:
- If the sum does not exceed the rate limit, the request goes through.
- If the sum exceeds the rate limit, the
request does not go through and you receive the following error message in UiPath Studio:
Error: Rate limit exceeded. If you're on a free tier, consider upgrading to paid license. If already on a paid license, please contact UiPath for further upgrade options.
Given the fact there is a one minute sliding window rate limit and the requests are retried, for a failed request to go through, more bandwidth needs to become available.
Let's take the example below:
12:00:00 - image request 5MP >> 25MP available
12:00:01 - image request 5MP >> 20MP available
12:00:02 - image request 5MP >> 15MP available
12:00:03 - image request 5MP >> 10MP available
12:00:04 - image request 5MP >> 5MP available
12:00:05 - image request 5MP >> 0MP available
12:00:06 - image request 5MP >> failed request - no more quota left
...
12:01:00 - 5MP available12:00:00 - image request 5MP >> 25MP available
12:00:01 - image request 5MP >> 20MP available
12:00:02 - image request 5MP >> 15MP available
12:00:03 - image request 5MP >> 10MP available
12:00:04 - image request 5MP >> 5MP available
12:00:05 - image request 5MP >> 0MP available
12:00:06 - image request 5MP >> failed request - no more quota left
...
12:01:00 - 5MP availableSo, in this example, the 12:00:06 request can only go through at 12:01:00.
If you have an Enterprise license and you frequently reach the 240 megapixels per minute limit, please contact us.
